Homicide detectives are investigating a reported shooting that left a man dead in Logan Heights on Sunday, San Diego police said.

Someone called 911 to report gunshots on Sampson Street near South 28th Street about 8:10 p.m. When officers arrived, they found an injured 29-year-old man suffering from a gunshot wound to his upper body, said police homicide Lt. Anthony Dupree.

The wounded man was taken to a hospital, where he died. There were no other victims, police said.

Dupree told San Diego News Video that several shell casings were found in the street.

Officers know who the victim is but are not releasing his name until family members are notified, Dupree said.

The homicide was the third killing in the city on Sunday. About seven hours earlier, two men were fatally shot in a city park, about two miles from the Logan Heights incident.

Around 1:20 p.m., a gunman approached two men in front of the Mountain View Recreation Center, shot them and fled. The victims were taken to a hospital, but both died of their injuries.

The Mountain View killing may have been gang related, although it’s still under investigation, Dupree said.
